WALTER H. SHIMPF, OF NEW YORK, N. Y., ASSIGNOR T0 C. R. TEABOLDT, OF NEW YORK, N. Y;

SPRING-HOLDING DEVICE FOR VALVES.

b all whom it may concern..-

llc it known that I, WALTER H. Sumrr, a citizen of the United States, residing at'New York, in the county of New" York and State of New York, have invented new and useful Improvements in Spring-Holding Devices for Valves, of which the following is a specification.

The present invention relates to means for holding valve springs in compressed relation in order to permit the convenient removal of the valves, and the object is to provide a very simple device that can bekept in a repair kit, and can be readily applied to practically any form of valve mechanism for the above described purpose.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the device, showing the same in operative position. Fig. 2 is a bottom plan view of the same. Fig. 3 is an end elevation. Fig. 4 is a detail sectional view.

Similar reference numerals designate corresponding parts' in all the figures of the 4 drawings.

In the embodiment disclosed, a base lever 5 is employed having a pairof upstanding ears 6 at one end, and furthermore having a clamping bolt 7 threaded into said end trans versely of the lever. are a pair of relatively swinging bearing jaws 8,'tl1e upper jaw engaging the under side of the lever, and a washer 9 being interposed between the lower jaw and the head 10 of the bolt.

.An operating lever 11 is 'fulcruined, as shown at 12, to and between the cars, the portion of the lever that projects over the jaws 8 being disposed in angular relation to the main arm. of said lever and formed into a spring-pressing yoke 13. The ends of the yoke are rounded, as shown at 14, so as to have a sliding bearing against the washer 15, against which the spring 16 of the valve bears. The free-end-lof the lever 5 is pro vided with an eye 17,-land a holding link 18 swingingly mounted in this eye, is adapted to be swung over the free end of the lever 11, when said levers are together, thus hold- Specification of Letters Patent.

Application filed July 5, 1910. Serial No. 570,383.

Mounted on this belt Patented Jan. 24-, 1911.

The iisual valve rod is shown at 21, and

projects through a guide 22. In applying the device, the jaws 8 are adjusted so as to embrace the rod 21 and bear upon the guide The free ends of the yoke 13 are then placed behind or beneath the washer 1.5,the levers 5 and 11 being disposed in spaced relation. Said levers are then brought together, and the link 18 is swung to the position shownin Fig. l, whereupon the washer 15 will be raised from the pin, and the spring 16 compressed. The parts will be held in this position so that the pin can be readily removed, after which the valve can be easily abstracted.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be a parent to. those skilled in the art, without 'urther dcscription, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to within the limits of the appended claims without departing fromv the spir tor sacrificing any of the advantages of the invention. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A. device of the character set forth, comprising enacting levers and a bearing member carried by one of the lovers and comprising relatively adjustable jaws, the other lever having a spring pressing portion.

2. A device of the character set forth, comprising a lever, adjustable bearing jaws ivotally mounted thereon, another lever ulcrumed to the first lever, and a springprcssing oke carried by the other lever.

3. A 'evice of the character set forth, comprising a lever,a depending clamping relatian with the ether apable of swinging into "ra Sugar, r
